Pile Test Services
The Tube Wave Pile Integrity Test (TWPIT) evaluates pile integrity by analyzing tube waves generated from a single probe. This method detects structural anomalies and variations in pile quality, providing a detailed assessment with minimal equipment, even more comprehensive compared to USPIT and LSPIT.
| Aspect | Description |
|---|---|
| Test Name | Tube Wave Pile Integrity Test |
| Test Purpose | To assess the integrity of a pile by analyzing the propagation of tube waves generated by single sensor inside the pile. |
| Test Standard | Custom or project-specific standards, as this method is less standardized. |
| Test Procedure | Single probe lowered down at centre of pile. |
| Load Application | Load is applied using a single probe that act as sender and receiver. |
| Test Measurement | Time of flight and wave amplitude are analyzed to assess pile integrity. |
| Key Parameters | Wave propagation speed, reflection characteristics, and defect identification. |
| Test Duration | Typically ranges from several minutes, depending on pile length. |
| Load Application | Single probe lowered down at centre of pile. |
| Test Applications | Load can be applied using hydraulic jacks against a reaction frame, dead weights, or Kentledge blocks. |
| Test Advantages | Comprehensive signal hence produce more accurate compared to USPIT and LSPIT |
| Test Limitations | Interpretation of results can be complex, and the method may be less effective in certain soil conditions. |
